vhdl经典源代码――ps2接口设计，入门者必须掌握-vhdl classical source code-- ps2 interface design, beginners must master

ALTERA 的关于对SDRAM控制器操作的verilog相关程序，很不错绝对值得借鉴。-ALTERA on the operation of the SDRAM controller Verilog procedures, it is definitely worth a good draw.

本人写的数字锁相环，有模拟数据，学习锁相环很好的材料。参考书“数字锁相环路原理与应用”编写。-I write the digital phase-locked loop, have simulated data, a good phase-locked loop learning materials. Reference book

vga interface with text rom. font size 80x40. core need core regeneration.

verilog写的39阶通带为20KHz的半带fir滤波器，经测试正确。(verilog halfband FIR)

典型事例，从网上down的，希望对大家有用，-Typical examples, from the Internet down, and I hope useful for everyone,

基于ALINX AX7020硬件平台的USB-OTG通信程序。操作系统采用uCOS III v1.41，基本实现了双向USB2.0 块传输（Bulk Transfer）通信，zynq的PS端接收USB数据并回传至主机。经测试，主机端Window10系统采用libUSBK编程时，采用64字节的块时，传输速率可达210Mbps。zynq开发工具为Vivado2015.4，程序包中包含了全部的硬件和软件工程文档。(A USB-OTG communication project where an AX7020 platform is employed as USB device. The embeded operating system is uCOS III of version 1.41, and the FPGA toolchain is Vivado 2015.4. This project implements a full speed bidirectional USB2.0 bulk transfer. A test on Windows 10 host with libUSBK shows that the transfer speed is up to 201Mbps.)

pci协议主模块开发实用代码， 适合初级学习者使用 很不错(pci agreement to develop practical code, very good for junior learners)
